conveying information, indicating an action, prompting a
response, or distinguishing a visual element.
There should be additional visual cues for any element
where you would only use color to indicate that it is
interactive.

The contrast ratio between text and a text’s background
should be at least 4.5:1. If your font is at least 24px or 19px
bold, the minimum drops to 3:1.

paragraphs, and paragraph spacing is at least 1.5x larger
than the line spacing.
Text should not be all caps nor should it be justified (i.e.,
